Changes proposed in this Pull Request:

• This PR adds a util deferExecution(), a workaround that defers execution to the next event loop cycle to ensure state updates are committed.
• I'm fixing this using a workaround because I could not find a proper fix.
• The PR also removes a redundant file.

Things I tried that did DID NOT work.

1. Using useRef() to persist the Token.
2. Using useTransition() to prioritize state updates.
3. Using the Functional Updater Pattern: setTokenResult( ( prev ) => newToken ).
4. Moving onSubmit() inside useEffect().
5. Using queueMicrotask() to delay execution.

Closes #214
Closes #307

Steps to test the changes in this Pull Request:

• Test Digital Wallets and CashApp.
• Wait for E2E tests to pass.

Thank you for the workaround @Sidsector9 I think it's a valid, clean hack. I haven't tested the flow but the code make sense to me.
